Wave–particle duality
I removed the material you added to Wave–particle duality, because it looked like it was copied from somewhere else. Don't copy material from other sources directly into Wikipedia. Generally, such material is protected by copyright. We take copyright very seriously and do not violate others' copy rights. Everything on Wikipedia needs to be written fresh or made available under an open license.--Srleffler (talk) 20:33, 8 February 2020 (UTC)
